Introduce "add-type-to-class-name" option to Ng Generate Application and Ng New

### Command

new, generate

### Description

To enhance Angular CLI so that developer can control whether the app component generated during ng new or ng generate application will have the Type appended to its class name (i.e AppComponent) or not.

In addition, to allow developer to set a default angular.json's schematics **"addTypeToClassName" to true** via command line, so that future creation of component (include service and directive) via CLI will by default include the type inside the classname.

### Describe the solution you'd like

1. introduce **add-type-to-class-name** option to Ng Generate Application and Ng New, OR
2. rename the "file-name-style-guide" option to "style-guide", with 4 possible values
**addTypeToClassNameOnly**, **addTypeToFileNameOnly**, **addTypeToFileAndClassName**, **2025**

Doing so, will set the **addTypeToClassName to true** inside the angular.json for component, service and directive

### Describe alternatives you've considered

Currently, developer has to manually change the class name for the App Component to include the Type

Start with the ng new and ng generate application command entry points and the angular.json schematics configuration described in the issue. Trace how application options are applied, then verify that the requested option can set addTypeToClassName for future component, service, and directive generation.
